What material is the gearbox? The next should be cut and shut in my opinion, but I don't know how to weld it yet. Could anybody tell me/_________________1973 BayWindow running 1.9 110 bhp TDI with flipped gearbox.

also, I want to relocate the breather, but what would be a good spot for this? with the box out, I can make it anywhere but what would be the best choice?_________________1973 BayWindow running 1.9 110 bhp TDI with flipped gearbox.

The cut and shut method I think is done by holding the gearbox square. And using a big bandsaw. The bell housing cut off.
Then it is rotated and ‘welded’ back on at the desired angle.
180 degrees for the ‘upright’ installation.

I have heard of some people using a large angle grinder held in a jig.
But never seen it done or seen results. Maybe you could hold the angle grinder on a set frame and the gearbox on a rotating base. And rotate the gearbox as you cut it.

Will get a picture of it for you shortly. I’m currently fitting a charge cooler.

I also have a new ECU.... from a ABL engine??? 80pin to 120 pin conversion is needed for this. No idea I was virtually given it by my friend. Now PD Inlet manifold also, guaranteed 3.7 extra HP _________________Think......

I have used this place for a breather. Copied from an guy from Austria, who ran 6000 km without losing any gearbox oil. First picture is outside view, second is inside gearbox to show where the breather goes.

I also addresse another issue with the adapter plat. As Splitbusvanatic once pointe out, the gearbox connection to the adapter plate is not optimal. One half is fixed properly, but the other half of the circumference of the bellhousing does not have a bolt connected to the adapter or the engine.

He showed this in the picture below. The red arrows indicat where he thougt of putting extra bolts.

the adapter plate bolts nicely to the engine, all the way around. The gearbox not so much to the adapterplate, as said above. But at the point of the yellow circle, ther is room to weld a thick bolt to the adapter plate, which will allow you to use a hole on the bell housing. Just shove the box over the bolt and put a nut on it, and you can fix the box a lot better.

And what else...

I ran the engine without mufflers. It was not that loud, so I decided to get rid of the muffler and just fabricate an exhaust of about 1 meter long, and rout it directly to the back, just under the rear bumper. So that is a simple curved steel tube without anything else. the turbo reduces virtually all noise of the engine. This way, I could get rid of the large muffler I had, and was not happy with as there is hardly any room. And it is absolutely not any louder.

Almost finished, will try to take a pic tonight._________________1973 BayWindow running 1.9 110 bhp TDI with flipped gearbox.
